WATER-USE REQUIREMENTS ASSOCIATED WITH HYDRAULIC FRACTURING WITHIN THE WILLISTON BASIN
To date, there has been limited analysis of the amount of water used for hydraulic fracturing. Data that identify the factors (technological, geological, and geographic) that influence the amount of water used for hydraulic fracturing at each oil and gas site is particularly lacking in analysis. Additionally, little is known about the partitioning of disposal methods, including recycling. This lack of information prohibits fact-based management of the groundwater and surface water resources.
The objectives of this ongoing investigation are to (1) obtain and analyze water-use data at a well site (process) level and (2) identify the primary factors (predictor variables) controlling water use. Using available and surveyed water-use data, mathematical relations are being developed between the predictor variables and water-use quantities. These relations will then be used to estimate water-use requirements in the Williston Basin with respect to ongoing and future hydraulic fracturing and provide data for concurrent groundwater modeling studies to estimate groundwater availability under various development scenarios.
